Sale, who was supposed to start Monday against the Jays, will now start Tuesday, Paul Skrbina of the Chicago Tribune reports.
There does not appear to be any sign of injury here, so manager Robin Ventura may simply be inserting a sport starter to give the remainder of the rotation rest in a month that has featured few off days. Erik Johnson (currently in the bullpen) and Miguel Gonzalez (currently at Triple-A Charlotte) are the top two candidates for Monday's nod.
